KVM: selftests: Add helper for enabling LPIs on a redistributor
...
The selftests GIC library presently does not support LPIs. Add a
userspace helper for configuring a redistributor for LPIs, installing
an LPI configuration table and LPI pending table.

KVM: selftests: Add a minimal library for interacting with an ITS
...
A prerequisite of testing LPI injection performance is of course
instantiating an ITS for the guest. Add a small library for creating an
ITS and interacting with it from the guest.

KVM: selftests: Standardise layout of GIC frames
...
It would appear that all of the selftests are using the same exact
layout for the GIC frames. Fold this back into the library
implementation to avoid defining magic values all over the selftests.
This is an extension of Colton's change, ripping out parameterization of
from the library internals in addition to the public interfaces.

KVM: arm64: selftests: Add basic GICv3 support
...
Add basic support for ARM Generic Interrupt Controller v3.
The support provides guests to setup interrupts.
The work is inspired from kvm-unit-tests and the kernel's
GIC driver (drivers/irqchip/irq-gic-v3.c).
